LOCOMOTIVE-VJHEEL-HUB LINER.

Application filed June 18,

To all whom it may concern:

Be it known that 1, JOHN BAKER liLlICHAEL, a citizen of the United States residing at Selma, in the county of Dallas and State of Alabama, have invented a new and useful Locomotive-Whoel-Hub Liner, oil? which the following is a specification, reference being ba l to the accompanying drawings and. to the letters and figures oi reference marked thereon.

This invention relates to a liner that is designed to be used instead oi the liner that ha hitherto been secured to a wheel hub or to an adjacent journal box, or to both the hub and the box to reduce lost motion or excessive play between the hub and the box due to wearing away of the faces of such parts in contact each with the other, the invention having reference more particularly to a sectional hub liner that is designed to be placed on an axle or shaft between a hub and a journal box Without removing either the axle or the journal box from the proper relative position thereof in the machinery.

An object of the invention is to provide an improved sectional hub liner or space filler of the above-mentioned character which shall be so constructed as to be suitable tor use between the hubs of drving wheels or truck wheels and the adjacent journal boxes of locomotives particularly. and without necessitating loss oi time and service of the locomotive with the excessive cost of labor incidental to the removal of the wheels and associated parts from their place in the locomotive.

Another object is to provide a sectional hub liner of the above-mentioned character which shall be so constructed as to permit it to be quickly placed on an axle between a hub and a journal box. and which shall have reliable means and a safety guard whereby to secure the sections of the liner firmly together so as to be dependably kept in place under severe conditions incidental to the operation of locomotives on railroads.

A further object i to provide a sectional huh liner which shall be so constructed as to be strong. and which shall have a plurality of series of devices whereby to reliably secure the sections of the liner together and to an axle so that the liner will not be liable to drop oil and be lost from the axle in case 1321. Serial No. 478,767.

one of the securing devices becomes broken in use or fails to perform its function.

A still further object is to provide a sectional hub liner or space filler which shall be oi. such design as to permit of its manufacture at small cost and yet be strong, and permit of its being quickly applied and securely tastened in place, and which shall be iapuble of long service and be economical in use.

ll ith the above mentioned and other object in view, the invention consists in a hub liner of annular plate form or contour, having a small removable section normally keyed in the liner and rigidly secured in place; and, the invention consisits also further in the novel pa ts and in the combinations and arrangements of parts as herein after particularly described and further defined in the accompanying claims.

Referring to the drawings -Figure 1 represents a pair of locomotive wheels on an axle which supports two journal boxes and a pair of the improved hub liners arranged between the wheel hubs and the journal boxes; Fig. 2 is a plan of the improved hub liner preferably constructed; l 3 is a fragmentary sectional view of the in iroved liner on a plane midway. between the two working faces of the liner; Fig. 4c is a perspective view oi the hub liner as essentially constructed. minus the devices which may be varied for securing the sections of the liner together; Fig. 5 is a fragmentary peripheral or edge view of the im proved liner; 6 is a plan view of the liner slightly modified as to details relating: to devices for securing the sections of the liner together; Fig. '7 is a peripheral or edge view of the liner as shown in Fig. 6; Fin. 8 is a section approximately on the line Vlll'.VllI in Fig. 6; Fig. 9 is a perspective view of the main part of the hub liner lightly modified; Fig. 10 is a perspective view of the removable section of the modified liner; Fig. 11 is a plan of one of the devices for securing; the sect-ion in the main part oi the hub liner. broken lines indicating the term of the device when finally completed to perform its functions; and. Fig. 12 represents the modified form of liner in place between. a wheel hub and a journal box.

imilar reference characters in the difrcnt figures the drawings indicate corresponding elements or features of the invention herein referred to in detail.

In the drawings the numeral 1 indicates an axle or shaft, 2 and 3 indicate wheels fixed on the axle and. having hubs i and 5 respectively, which when newly installed are directly engaged by journal boxes 6 and 7 on the axle to limit the movement of the boxes longitudinally of the axle.

The improved hub liner essentially comprises amain part or plate which consists of a semi-circular body portion 8 and two limbs 9 and 10 With a suitable space between the limbs sothat the main part has a gap or opening in it extending. inwards from the edge or peripheral portion of the part, the edges ofthe plate or part at opposite sides of:' the opening being straight and parallel. The body portion has a concave inner edge 11 designed to conform to the axle on which the liner is to be used. At the inner end of the opening in themain part or plate two stop shoulders 12 and13 are provided and the straight edges at the sides of the opening have suitable guide faces, preferably grooves 1e. and 15 respectively of V-shape transversely. A removable liner section 16 is provlded which has two guide faces 17 and 18 on opposite sides thereof conforming to the guides 14 and respectively, so that when the section isinserted in the openor gap in the main part the section shall be laterally retained in place. The inner end of the removable section has a concave edge 19- and oppositely arranged limbs 20 and21 that are stopped against the shoulders 3.2;and 1.3 respectively, resulting in the edges 11. and 19 together.forming a cylindricalibore closely corresponding to the diameter. of the axle.

I The section 16 of the liner is required to be firmly bolted or pinned to the main part of the liner and has. preferably two holes 22 and???) therein from which bolt holes-E245 and 25 evtendv respectively t-o-siinilar holes 26 and 97 that are provided in the limbs 9 andlO respectively. Preferably the limbs have recesses 28 and 29in the outer or peripheral portion thereof that extend circuniferentially from the holes 26 and 27 respectively. A red or pin 30 is inserted in the holes 26 and2 i, and a rod on pin 31 is inserted in the holes 27 and 25. The outer ends of the rods have lieadportions andt33 thereon that are received'in the recesses 28 and-29 respectively and the inner ends of the rods which appear in the holes 22 and 23have heads 34 and respectively that are. formed by bending the rod, preferably after heating the rod, so that the lIQQCl POIiZlOllS in the holes shall draw the metal and tend to draw the limbs 9 and 10 towards the removable section of the liner, in order that the limbs shall. not be liable to be broken off from the main portion 8.

Preferably the periphery of the liner has a groove therein, there being: a groove 36 be forcibly sprung into or out of the groove,

and. in some cases it may not benecessary that the entire band be coiled.

In somecases the section 16 is provided with one hole 41: from which extend p1n holes 24: and 25 so as to be in alinement with pinholes 26 and 27 provided inthe limbs 9 and 10 respectively, and two pins on reds i2 and 43 are arranged in the pin hcles and preferably are connected to a loop 431 which is formed by bending headportions on the pins or rods within the hole 41, the head portions securely retaining the pins or rods in place.

/V hen desired a slightlydifferent safety guard banding device than thatdescribed" maybe provided, and to this endthe body portion 8 of] the main part or plate is prov. led with two sockets 45 and 46 extending from the bottom of the groove 36, and two clasp arms or banding sections 47; and 48 are arranged in the groove so as to engage and. retain the section 16, and the arms are preferably integrally connected to a spring loop 49 permitting the arms, to be forcibly sprung out of place when necessary, the ends ofthe armshaving'lugs 50 and a1 thereon that are inserted in the sochets and 4:6, respectively. The body portion 8 preferably has also two notches 52 and 5.3-therein ad jacent to the sockets and-so as to becovered by the arms, to receive a tool whereby to force one arm; outwards to draw the lugfrom thesocket' when required.

. In practicaluse a liner of: proper thickrises to reduce the space betweenthehub and the journal box to the desired extent; is selected from stock, and after separatingtheill? parts of the liner the mainpart is placedinl the required position onthe ax'le on shaft, after which the. removable section is inserted into the main part. When thep'ins or rods for securing the section in place are made separately they are inserted through the pin-holes 26 and 27: respectively, after which the head portions: and 35" are! formed by'bending therods which mayhave been previously heated. When additional safeguard'isdesired the band or elasp device maybe applied, and'so as to retain thesecur ing pins or rods in place, as above described.

When the pins 42 and 48 are preferred a straight rod is first inserted in the pin-holes, after which the middle portion of the rod is bent in the hole 41. to form the head portions and loop 44, the bending being mor easily done if the middle portion ot the rod is first heated. In the operation of the locomotive or a machine the side faces of the liner will be worn away while the faces of the hub and the journal box are also tn ther worn away, until an excessive amount or lost motion again develops. The liner may become worn until in some cases it becomes quite thin, affecting its stability materially or impairing the efiiciency ot the device for securing the parts of the liner together. Finally, when a thicker liner is required it may be readily applied as is apparent a'tter first removing the old liner. In some cases the old liner may be useless for further service and may be readily broken up by force to permit it to be quickly removed from place.

Under the severe conditions imposed upon the liner in operation, the securing pins or rods or portions of the liner adjacent thereto may possibly be broken so as to impair the securing devices, but the safety guard band may in such case be relied upon to at least temporarily hold the parts of the liner together and on the axle, or until customary inspection is made and the damage repaired, Without serious risk of the liner falling oil and causing derailment or the locomotive or train.
